我有一個web服務，它搜索modeshape內容存儲庫中的文本片段。 接口看起來是這樣的：其他web服務不返回任何結果
@POST
@Path("globalSearch")
@Consumes(MediaType.TEXT_PLAIN)
@Produces(MediaType.TEXT_XML)
public String globalSearch(String search) {
XMLConverterService xmlOb = new XMLConverterService();
Map<String,String> param = xmlOb.fetchMapFromXml(search);
StringBuffer xmlString = new StringBuffer();
xmlString.append("<xml>");
int count = 0;
List<Map<String, String>> result = (new DataInterfaceService())
.fetchGlobalSearch(param);
if(result!=null){
for (Map<String, String> map : result) {
count++;
xmlString.append("<result" + count + ">")
.append(xmlOb.fetchXmlFromMap(map))
.append("</result" + count + ">");
}
xmlString.append("</xml>");
return xmlString.toString();
}
return null;
}
的fetchGlobalSearch（）函數看起來是這樣的：
public List<Map<String, String>> fetchGlobalSearch(Map<String, String> param) {
logger.log(Level.INFO, "entering fetchGlobalSearch");
String keyWord = param.get("keyword");
String type = param.get("type");
List<Map<String, String>> listOfMaps = null;
Map<String, String> retValue = null;
String qry = "";
if (type.equalsIgnoreCase("GRA")) {
qry = "SELECT [med:UNIQUE_ID],[med:GRPNAME],[med:CSR],[med:UW],[med:GROUP_STATE],[med:STR_DATE] "
+ "FROM [med:notes] where contains([med:XML_STORE], $uuid)";
} else {
qry = "SELECT [fur:UNIQUE_ID],[fur:MM],[fur:FROMUW],[fur:INSURED],[fur:POLICY_NUM],[fur:UWCSRDATE],[fur:FURCOMPDATE],[fur:FUR_DATE],[fur:CSRCOMPDATE] "
+ "FROM [fur:notesfur] where contains([fur:XML_STORE], $uuid)";
}
try {
Query qr = qrym.createQuery(qry, Query.JCR_SQL2);
Value uid = session.getValueFactory().createValue(keyWord);
qr.bindValue("uuid", uid);
QueryResult resultSet = qr.execute();
String[] columns = resultSet.getColumnNames();
RowIterator rowiter = resultSet.getRows();
while (rowiter.hasNext()) {
if (listOfMaps == null)
listOfMaps = new ArrayList<Map<String, String>>();
retValue = new HashMap<String, String>();
Row row = rowiter.nextRow();
for (String column : columns) {
if (row.getValue(column) != null) {
retValue.put(column, row.getValue(column).toString());
}
}
listOfMaps.add(retValue);
}
} catch (RepositoryException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
logger.log(Level.INFO, "exiting fetchGlobalSearch");
return listOfMaps;
}
我用下面這段代碼訪問web服務：
private static void callGlobalSearch(){
try {
String param = "";
param = fetchGlobalParams();
System.out.println("param : " + param);
// Create a socket connection to the host
URL url = new URL(
"http://localhost:8080/xxttrr/rest/globalSearch");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
// make url connection
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);
conn.setAllowUserInteraction(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type",
"text/plain; charset=utf-8");
conn.setRequestProperty("Content-Length", Integer.toString(param.getBytes().length));
DataOutputStream printout = new DataOutputStream (conn.getOutputStream());
printout.writeBytes(param);
printout.flush();
printout.close();
BufferedReader in = new BufferedReader(new java.io.InputStreamReader(conn.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
System.out.println(line);
}
in.close();
conn.disconnect();
} catch (Exception e) {
System.out.println("Error: " + e);
}
}
的問題是當我對本地的modehape存儲庫進行web服務調用時，結果按預期返回。但是當我在DEV服務器上部署的代碼它形成以下日誌：

和終止。
這是與模式配置或web服務有關嗎？ 只是爲了讓你知道，在一個點上，modehape中可能會有一百萬條記錄。導致問題的超時也是如此。如果是這樣，那麼我怎樣才能配置我的web服務，使其能夠活5分鐘？
任何幫助，將不勝感激。 對於同一代碼在不同服務器中的行爲方式，真的很讓人困惑。
一些最重要的部分缺失 - 其餘服務的內容在哪裏？此外，您不希望服務試圖返回「數百萬」行數據。您需要以某種方式對結果進行分頁，以使服務更加可用。 – mikemil
嗨Mikemil， web服務不返回百萬條記錄。它只是在一百萬條記錄中搜索。一次web服務應該返回最多20條記錄。我在我的主帖中粘貼了界面的代碼。希望它能幫助你找出問題所在。 – TusharPanda
